我县现有柑桔面积4,004亩,其中开采面积仅有800亩左右,常年产量均徘徊在70万斤上下。低产的主要原因是由于过去肓目向外引种,品种繁杂,来源不明,因此在生产上出现大量适龄不结果,产量不稳定和品质低劣等问題。有的种植十多年了,还是“站岗树”,影响了社队经济收入和群众对种植柑桔的信心。为了进一步加速发展我县柑桔生产,建立高产稳产的柑桔优良品种基地,我们在柑桔品种较多的建设、火星、畔溪、官庄、洋枋等五片180亩老果园进行选种工作。1979年在群众初选的基础上,配合老果农对宽皮桔类和橙类,进行逐株考察,现场评比,果实鉴定以及果品分析测定等工作,共复选出建蜜2号、建芦2号、火红1号、畔雪1号、火雪1号、新会 My county existing citrus area of ​​4,004 acres, of which only 800 acres of mining area, perennial output are hovering at 700,000 pounds. The main reason for the low yield is the introduction of many species from the past due to its wide variety and unknown sources. As a result, a large number of problems such as age-appropriate results, unstable production and poor quality have emerged in production. Some planted more than a decade ago, or “standing tree”, affecting the community’s economic income and the masses of confidence in planting citrus. In order to further accelerate the development of citrus production in our county and establish a high-yield and steady production base of citrus varieties, we selected five 180-year-old orchards in areas with more citrus varieties, such as Mars, Banxi, Guanzhuang and Yangliu jobs. On the basis of the primaries of the masses in 1979, we cooperated with the old peasants on the wide-skinned oranges and oranges to carry out individual inspection, on-site assessment, fruit identification and fruit analysis and determination.
